Understanding Martyn’s Law

Martyn’s Law, formally known as the Terrorism (Protection of Premises) Act 2025, is new UK legislation designed to improve public safety by ensuring that venues and organisations are better prepared to respond to a terrorist incident.

The law is named in memory of Martyn Hett, one of the 22 people who lost their lives in the Manchester Arena terrorist attack in 2017. Following a long campaign led by his mother, the legislation received Royal Assent on 3 April 2025.

What is the purpose of Martyn’s Law?
The legislation aims to improve preparedness and help protect the public by ensuring that certain venues and events have plans and procedures in place should a terrorist attack occur. It focuses on practical measures that can help save lives, reduce harm and support an effective response during an emergency.

Who does it apply to?
Martyn’s Law applies to certain publicly accessible premises and events across the UK where significant numbers of people gather.

The requirements are based on the number of people who may reasonably be expected to be present:

• Standard Tier – premises where 200 to 799 people may be present.
• Enhanced Tier – premises where 800 or more people may be present.
• Larger venues and events have additional responsibilities to assess potential vulnerabilities and consider appropriate security measures.

What will organisations need to do?
Depending on their size and type, organisations may be required to:

• Have clear procedures for responding to a terrorist incident.
• Ensure relevant staff understand those procedures.
• Consider evacuation, lockdown and communication arrangements.
• Take reasonably practicable steps to reduce risks and vulnerabilities.
• Review and maintain preparedness plans.

When will the requirements come into force?
Although the Act became law in April 2025, the UK Government has indicated that there will be an implementation period of at least 24 months before the legal requirements come fully into force. This is intended to give organisations time to understand their responsibilities and prepare accordingly.

Why is this important for communities?
While the likelihood of a terrorist incident remains low, experience has shown that attacks can occur in a wide range of public places. Martyn’s Law seeks to ensure that venues, event organisers and those responsible for public spaces have considered how they would respond in an emergency, helping to improve public safety and resilience across communities.
